What is the name of the housing of a car air filter element
Air filter housing or air filter housing
The housing of an automotive air filter element is usually called air filter housing or air filter housing . The specific names may vary slightly depending on the model or brand. Here is a detailed description:
Youdaoplaceholder0 Common name
In the field of automotive maintenance and parts, this component is most commonly referred to as an air filter housing or air filter shell. For instance, on JD.com products, it is marked as "Yusenyi is suitable for both new and old Chevrolet Aveo air filter shells, air grids, air enclosures, and air filter shells." Some users also simply refer to it as "air filter box".
Youdaoplaceholder0 Function and structure
The housing is used to accommodate the air filter element, protecting it from external impacts and ensuring that air enters the engine through the filter element rather than bypassing it.
Some vehicle models also integrate an intake silencing device into their shells to reduce noise.
The materials are mostly plastic (such as nylon) or metal (metal casings may be adopted in the high-pressure environment of electronic fuel injection engines).

When replacing, pay attention to the model matching. The shape and fixing method of the shell may vary among different models (such as the special shell for Chevrolet Aveo mentioned in the search results).
Regularly check the sealing of the casing. Damage or deformation can cause unfiltered air to enter the engine, affecting its performance.
For further information, you can search for the air filter housing accessories of specific vehicle models or refer to the illustration instructions in the maintenance manual.
If the cover of the air filter box is not tightly closed, it will have a significant impact on the engine. Due to poor sealing, dust and sand particles will enter the combustion chamber unimpeded, accelerating the wear of internal engine parts. In severe cases, it may even lead to cylinder pulling. Further, this situation may also trigger a crisis of engine oil burning. For such problems, it is recommended to carry out timely maintenance to prevent further damage to the engine.
When conducting the inspection, the first thing to pay attention to is the cleanliness of the throttle body and the intake passage. If necessary, a deep cleaning should be carried out. If the intake valve is severely contaminated, an endoscope should be used to conduct a detailed inspection of the cylinder. If any impurities are found remaining, they also need to be thoroughly cleaned.
However, if the endoscopy examination shows abnormal wear of the cylinder, simple cleaning cannot solve the problem and further measures must be taken. To protect the engine, it is recommended to seek professional car repair services immediately to ensure that the problem is properly resolved.
The main function of the air filter element is to purify the air entering the engine. During operation, the engine needs to draw in a large amount of air, which usually contains impurities such as dust, pollen, sand grains, industrial waste gas, moisture and even cooking fumes. If untreated air directly enters the engine combustion chamber, it will not only affect the fuel combustion efficiency, but also may cause wear on the cylinder wall and piston rings, thereby affecting the engine's compression ratio, power output and fuel consumption level.
The core functions of the air filter element include:
Filter air impurities and protect engine parts: Prevent dust particles from entering the cylinder and wearing components;
Optimize the air-fuel mixture ratio: Maintain a stable intake air flow rate to enhance combustion efficiency;
Improve fuel economy: Purified air helps fuel burn completely and reduces consumption.
Reduce emission pollution: The improvement of air cleanliness can reduce the emission of harmful substances in exhaust gas.
Extend the service life of the engine: Reduce mechanical wear and lower the failure rate.
The structure and materials of the air filter element
The air filter element is mainly composed of filter paper (or other filtering materials), plastic frames, rubber sealing rings, etc. Common filter materials include cellulose paper (wood pulp paper), synthetic fibers (such as polyester), non-woven fabric materials, etc. The filter paper has undergone creasing treatment, which increases the filtration area and efficiency.
Modern high-end models even adopt high-efficiency air filters (HEPA level), which can filter fine dust particles of PM2.5 level, and are particularly suitable for urban or dusty environments.
Classification of air filter elements
According to the installation location and usage environment, air filter elements can be roughly classified into the following categories:
Dry air filter element
The most common type relies on filter paper or synthetic fibers for physical filtration, without the need to add lubricating oil, and is easy to replace and maintain.
Wet air filter element
The surface of the filter element is coated with special grease, which can effectively adsorb fine dust particles and is commonly found in motorcycles or off-road vehicles.
High-performance competitive filter element
Designed specifically for racing cars or high-performance engines, it features a large filtration area and high air flow rate, and often adopts a multi-layer sponge or cotton yarn structure.
Activated carbon air filter element
In addition to filtering dust, it can also adsorb odors and harmful gases in the air and is widely used in vehicle air conditioning systems.
